I agree that a battery can be somewhat reconditioned by replacing bad cells and equalizing the acid. But they say that they cut each cell open, clean the plates and put some magical elixir in and whamo the battery is renewed and carries a 4 year warranty. You can check them out at newlifebatteries dot com. I have already lost a deal to them. Unfortunately, when times get tough people flock to those that tell them what they want to hear....and most of the time they don't come back because they don't want to lose face.
